There’s no question we’re overdue for a good biopic of Cesar Chavez, the inspirational labor leader, civil rights activist, and co-founder of the United Farm Workers union. To keep his memory alive, it’s not enough for every U.S. city of reasonable size to name a street after him. Still, there is the inherent problem of figuring out how to fashion an engaging drama about a figure whose primary tactics involved nonviolent demonstration, economic boycott, and personal fasting (although 1982’s multi-Oscar-winner Gandhi proves that making such a film is not an impossible task). Cesar Chavez, though respectful and illuminating, never rises to the inspirational level of its titular subject.

Cast in the lead role for once, Michael Peña performs solidly as Chavez. An even temper keeps the character’s anger in check. Yet, the screenplay (by Keir Pearson and Timothy J. Sexton) defaults toward hero worship. Chavez’s worst characteristic in their script is that he sometimes overlooks his family’s needs in favor of his commitment to la causa. As his wife Helen, America Ferrara is nothing but supportive. Rosario Dawson plays Dolores Huerta, Chavez’s co-founder of the the UFW, but her role is underwritten, which makes Huerta seem like the real unsung hero of the movement. As one of the obdurate farm owners, John Malkovich venomously curls his lip and fails to see the parallel between his family’s immigrant experience in America and that of the Mexican-American farmworkers.

Actor Diego Luna (Y Tu Mamá También, Milk) takes the director’s reins for Cesar Chavez. And although this film seems for all concerned to be a passion project, there is little of that passion emanating from the screen. A great amount of political activity occurs over the course of the few years depicted in this movie and, consequently, much of the hard work of labor organizing, uniting fearful migratory workers, and orchestrating a national grape boycott falls by the wayside. In the end, viewers are more likely to draw inspiration from the vast number of national street signs bearing the Chavez name than from this deferential biopic.
